Builds as 64bit only so make sure you have propper firmware!
sync omni source
Refer to http://source.android.com/source/downloading.html Refer to https://github.com/omnirom/android
$ repo init -u git://github.com/omnirom/android.git -b android-11
If you want to use the contents of omni-private.xml please check https://github.com/omnirom/android/README and head over to send us a short email notice. Otherwise you can simple remove the include of that xml file and build without
If you want to build with microG add the contents of
$ repo sync
Build Android source
Refer to http://source.android.com/source/building.html
prepare environment
$ export ROM_BUILDTYPE=<MICROG|WEEKLY> $ export TEMPORARY_DISABLE_PATH_RESTRICTIONS=true $ export ALLOW_MISSING_DEPENDENCIES=true $ source build/envsetup.sh $ lunch omni_rpi4-userdebug
build
Use -j[n] option with make, if build host has a good number of CPU cores.
prepare boot device (sdcard or USB device)
Devices with GPT partition table cant be used as an USB boot device You must use MBR (msdos) parition table
The boot devices MUST contain 4 partitions with the following layout (parition sizes here are the minimum - userdata should be made bigger if you have the space)
Device Start End Sectors Size Id Type boot 2 262145 262144 128M c W95 FAT32 (LBA) system 264192 4458495 4194304 2G 83 Linux vendor 4458496 4982783 524288 256M 83 Linux userdata 4982784 16777215 11794432 5.6G 83 Linux
THE PARTITION ORDER MUST BE LIKE THIS
Starting with android-11 project quotas are mandatory in userdata parition. Prebuilt images have it enabled but if you recreate your userdata you MUST enable project quotas with e.g.
tune2fs -O project,quota
boot order
Switching between booting from sdcard and USB is done in config.txt by enabling the needed overlay
...
booting from sdcard
dtoverlay=rpi-android-sdcard
booting from usb
dtoverlay=rpi-android-usb ....
You can still mess with the fstab if you want and dont use the overlay
Note
the files in scripts are what I use to create and update feel free to adjust and update to your needs if you want
